Patent CA-2237693-A1 (CA)
Title: High-penetration transmission method for a radiocommunication system
Inventor: DENT PAUL W
IPC: H04L1/08
Filed: 1996-10-25
Abstract: A method and system for increasing the signal margin of a radiocommunication link to provide a short message service which is reliable, even under non-ideal conditions. According to the method, an increase in transmission power is used in combination with bit repetition to increase signal margin without complications in the mobile unit design, significant delay, or co-channel interference. Where a more significant increase in signal margin is desired, when a longer message is required, or for voice messages, the message may be stored and the mobile unit alerted of the message.

Title: Method and apparatus for monitoring laser weld quality via plasma light intensity measurements
Inventor: SHIRK BRYAN W
IPC: G01J3/443
Filed: 1998-10-22
Abstract: A method and apparatus for monitoring the quality of a laser process such as a laser welding process comprises monitoring the light emitted from the weld plasma above the surface of the workpiece irradiated by the laser beam. The intensity of the light emitted from the plasma is compared to a predetermined value of the light emission as determined under process and workpiece conditions that produce welds of acceptable quality. Variations of the monitored light intensity greater than a preselected value can be valuated as unacceptable welds. Such variations can be caused by changes in the laser beam power, the workpiece speed, laser focusing problems, insufficient shield gas flow, workpiece deformation and weld contamination. The process monitors the light emission for a selected range of wavelengths that correspond to the major emission peaks of the light spectrum. The method enables in-process control of laser processes.

Filed: 1997-04-17
Abstract: An aquaculture system for growing aquatic animals such as fish and crustaceans is shown and described. A rigid walled floating tank (24) is positioned in a body of water (26), a volume of water being provided to the tank via a floating pump assembly (39) that is positioned in the body of water external to the tank. An inlet (30) of the pump assembly is movable and may be positioned in a desired location and depth of the body of water, such that clean water that is free of surface contaminants, and that is at a selected temperature, is provided to the tank. The introduction of new water to the tank displaces and discharges a volume of water from the tank, thereby renewing the oxygen source in the tank and removing solid waste products such as ammonia. Additional oxygen may be injected into the water at different locations via oxygen diffuser (58).

Title: Traffic cone
Inventor: BRAVERMAN JOSEF J
IPC: E01F9/688
Filed: 1999-01-06
Abstract: A traffic cone to delineate areas under construction and to channelize traffic. The traffic cone comprises of two pieces. A first piece is an integral body and base portion. A second piece is a separable and re-usable ballast workpiece.  The ballast can be made from various industrial scrap components such as recycled tires. from cars or trucks, conveyor belts, or industrial flexible profiles. The base portion is specifically configured to receive the ballast in a peripheral annular channel defined therein. The ballast weights the first piece and provides stability to it. A  central hole on the bottom of the base portion and an open portion of the annular channel provides access for the ballast to be inserted or removed when desired. An upwardly disposed lip prevents the ballast in the annular storage area from unintentionally being dislodged therefrom. The base portion is advantageously shaped to stop the roll of the cone when the cone is overturned on its side. The device has the advantages of having separable ballast being readily removable, and re-usable with less transportation costs than current existing devices.

Title: Anti-torsion dryer connection
Inventor: TUGGLE W GREGORY
IPC: F26B21/00
Filed: 1999-04-06
Abstract: An improved vent system has a rotatable connection between flexible conduits, which carry heated air from the dryer to an external location, such as the atmosphere. The vent system consists of a swivel coupler rotatably connecting a pair of flexible exhaust conduits, one of which is readily attachable to a dryer exhaust outlet, which discharges exhaust air from the dryer, and the other of which is readily attachable to an outlet pipe, which carries exhaust air from the flexible exhaust conduit through a wall and to the atmosphere. Each flexible exhaust conduit, which is laterally flexible and axially extensible, includes a segmented elbow allowing bending up to approximately a right angle in one direction. The swivel coupler includes a rotatable joint wherein an annular extension on one half of the connector travels in an annular indentation in the other half so as to enable rotation therebetween. Through a combination of the flexible exhaust conduit, the segmented elbows, and the swivel coupler, an easy-to-assemble vent system having relatively few parts can be efficiently and safely installed by installers possessing even low levels of skill.

Title: Method of making protected changes to data stored in a database as well as database system and network element equipped therewith
Inventor: RIETZKE ARNO
IPC: G06F11/14
Filed: 1999-06-09
Abstract: To change data in a database (DB) in such a manner that in case of a disturbance the database can be restored to an initial state, it is proposed to temporarily store the block numbers (BNO) of free memory blocks (BL*) in a nonvolatile semiconductor memory (NVM). In case of a disturbance, the free memory block (BL*) continues to be managed as a free memory block. In case of an undisturbed, successful change to the data, the memory block (BL) in which the old data were stored is deallocated. The invention is particularly suited for use in database systems for network elements of a digital communications network, particularly for crossconnects of an SDH network (SDH = Synchronous Digital Hierarchy).

Title: On-line control of a chemical process plant
Inventor: MCDONALD MICHAEL F
IPC: G01N21/35
Filed: 1997-12-31
Abstract: A process plant for the manufacture of halobutyl rubber is provided with online monitoring and control of the process parameters to control the properties of the product. It incorporates an in situ measurement system that does not require the removal of any sample material from the process. It uses a Fourier Transform Near Infrared (FTNIR) spectrometer, fiber-optic cables, a viscometer for measuring solution viscosity and a Resistance Temperature Device (RTD) for temperature measurement. An online real-time analyzer system using a Constrained Principal Spectral Analysis program predicts the property of the polymer product and provides the process control system with analysis of the data using derived relationships between the physical properties of the polymer and these spectral measurements and the measured values of fluid viscosity and temperature. Differences between the predicted and desired property of the product are used to control process parameters. The method can be used for a variety of chemical process plants.

Abstract: A technique for dynamic call processing which utilizes information collected from the calling party's information appliance to route an incoming call. A  variety of information is dynamically captured and stored by the calling party's information appliance, e.g., telephone, computer, set top box and the like, over time. The type of information includes, but its not limited to, items such as personal data, credit information, purchasing history, market study data, and geographical information. In accordance with the technique, when the calling party places a call to a call center location, the information stored in the calling party's information appliance is accessed and used to route the call to an appropriate agent in the call center.  Advantageously, incoming call center calls are dynamically routed without the reliance on static applications, databases or other traditional network management techniques.
